754952 ÷ 81 
The aim is to understand the frequency of 81 in 754952.

Moving on to step 1:
81 can be fit into 7 0 times, resulting in a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Include the next digit (5) from the dividend after 7, then repeat: 75 / 81

Moving on to step 2:
When dividing 75 by 81, we get 0 with a remainder of 75.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 75 to get 75.
Grab the next digit (4) from the dividend, add it to 75, then carry on: 754 / 81

On to step 3:
The number 81 fits into 754 9 times, leaving a remainder of 25.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
Deduct 729 from 754 and we're left with 25.
Include the next digit (9) from the dividend after 25, then repeat: 259 / 81

Let's proceed to step 4:
81 can be fit into 259 3 times, resulting in a remainder of 16.
Put 3 as the next digit of the answer. 
Result so far: 93.0
The remainder is 16 after subtracting 243 from 259.
Take the next digit (5) from the dividend and append it to 16, then repeat: 165 / 81

Step 5:
81 can be fit into 165 2 times, resulting in a remainder of 3.
The next digit of our result is 2. 
Result so far: 932.0
Subtract 162 from 165 to get 3.
Grab the next digit (2) from the dividend, add it to 3, then carry on: 32 / 81

Let's proceed to step 6:
If we divide 32 by 81, we get 0 and a remainder of 32.
The number 0 becomes the next digit in our result. 
Result so far: 9320.0
If we take 0 away from 32, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Advancing to step 7:
81 goes into 320 3 times with a remainder of 77.
The number 3 becomes the next digit in our result. 
Result so far: 9320.3
Subtract 243 from 320 to get 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

On to step 8:
81 goes into 770 9 times with a remainder of 41.
The number 9 becomes the next digit in our result. 
Result so far: 9320.39
The remainder is 41 after subtracting 729 from 770.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Going ahead to step 9:
81 goes into 410 5 times with a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 9320.395
The remainder is 5 after subtracting 405 from 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 10:
The number 81 fits into 50 0 times, leaving a remainder of 50.
The number 0 becomes the next digit in our result. 
Result so far: 9320.395
Subtract 0 from 50 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 11:
500 divided by 81 is 6 with a remainder of 14.
Put 6 as the next digit of the answer. 
Result so far: 9320.39506
Deduct 486 from 500 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 12:
When dividing 140 by 81, we get 1 with a remainder of 59.
Put 1 as the next digit of the answer. 
Result so far: 9320.395061
If we take 81 away from 140, we end up with 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Moving on to step 13:
When dividing 590 by 81, we get 7 with a remainder of 23.
Record the quotient 7 as the next digit in the result. 
Result so far: 9320.3950617
Subtract 567 from 590 to get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Advancing to step 14:
If we divide 230 by 81, we get 2 and a remainder of 68.
The next digit of our result is 2. 
Result so far: 9320.39506172
Subtract 162 from 230 to get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Our division results in 9320.39506172 with a remaining 6.8e-08.
